Wu F, Zhang X, Zhang S, Zhang Y, Feng Y, Jiang Z, Shi Y, Zhang S, Tu W. Construction of an immune-related lncRNA-miRNA-mRNA regulatory network in radiation-induced esophageal injury in rats. Int Immunopharmacol 2023; 122:110606. [PMID: 37423154 DOI: 10.1016/j.intimp.2023.110606] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Revised: 06/20/2023] [Accepted: 07/03/2023] [Indexed: 07/11/2023]
Abstract
Radiation-induced esophageal injury (RIEI) is an adverse reaction of radiation therapy in patients with esophageal cancer, lung cancer and other malignant tumors. Competitive endogenous RNA (ceRNA) network is known to play a significant role in the onset and progression of many diseases, but the exact mechanism of ceRNA in RIEI has not been fully elucidated. In this study, rat esophaguses were obtained after conducting irradiation under different doses (0 Gy, 25 Gy, 35 Gy). Total RNA was extracted and mRNA, lncRNA, circRNA, and miRNA sequencing was performed. Multiple dose-dependent differentially expressed RNAs (dd-DERs), including 870 lncRNAs, 82 miRNAs, 2478 mRNAs, were obtained through the integration of differential expression analysis and dose-dependent screening (35 Gy ≥ 25 Gy > 0 Gy, or 35 Gy ≤ 25 Gy < 0 Gy). Co-expression analysis and prediction of the binding site in dd-DER were conducted and 27 lncRNAs, 20 miRNAs, and 168 mRNAs were selected to construct a ceRNA network. As the immune microenvironment is crucial for RIEI progression, we constructed an immune-related ceRNA network consisting of 11 lncRNAs, 9 miRNAs, and 9 mRNAs. The expression levels of these immune-related RNAs were verified by RT-qPCR. Immune infiltration analysis showed that the RNAs in the immune-related ceRNA network were mainly associated with the proportion of monocytes, M2 macrophages, activated NK cells, and activated CD4+ memory T cells. Drug sensitivity analysis was conducted based on the expression levels of mRNAs in the immune-related ceRNA network, and small molecule drugs with preventive and therapeutic effects on RIEI were identified. In summary, an immune-related ceRNA network associated with RIEI progression was constructed in this study. The findings provide useful information on new potential targets for the prevention and treatment of RIEI.

Construction and validation of a competing endogenous RNA network in the thymus of miR-147 -/- mice. Int Immunopharmacol 2023; 117:109896. [PMID: 36812675 DOI: 10.1016/j.intimp.2023.109896] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Revised: 01/31/2023] [Accepted: 02/11/2023] [Indexed: 02/22/2023]
Abstract
BACKGROUND Prior evidence has demonstrated that miR-147 can regulate cellular proliferation, migration, apoptotic death, inflammatory responses, and the replication of viruses through its interactions with specific mRNA targets. LncRNA-miRNA-mRNA interactions are often found in various biological processes. No studies have documented lncRNA-miRNA-mRNA regulatory interactions in miR-147-/- mice. METHODS Thymus tissue samples from miR-147-/- mice were systematically analyzed to detect patterns of lncRNA, miRNA, and mRNA dysregulation in the absence of this biologically important miRNA. Briefly, RNA-sequencing was used to analyze samples of thymus tissue from wild-type (WT) and miR-147-/- mice. Radiation damage models of miR-147-/- mice were prepared and prophylactic intervention with the drug trt was performed. The validation of miR-47, PDPK1,AKT and JNK were carried out by qRT-PCR, western blot and fluorescence in situ hybridization. Apoptosis was detected by Hoechst staining, and histopathological changes were detected by HE staining. RESULTS We showed the identification of 235 mRNAs, 63 lncRNAs, and 14 miRNAs that were significantly upregulated in miR-147-/- mice as compared to WT controls, as well as 267 mRNAs, 66 lncRNAs and 12 miRNAs exhibiting significant downregulation. Predictive analyses of the miRNAs targeted by dysregulated lncRNAs and their associated mRNAs were further performed, highlighting the dysregulation of pathways including the Wnt signaling pathway, Thyroid cancer, Endometrial cancer (include PI3K/AKT) and Acute myeloid leukemia pathway(include PI3K/AKT) pathways. Troxerutin (TRT) upregulated PDPK1 via targeting miR-147 to promote AKT activation and inhibit JNK activation in the lungs of mice in radioprotection. CONCLUSION Together, these results highlight the potentially important role of miR-147 as a key regulator of complex lncRNA-miRNA-mRNA interacting networks. Further research focusing on PI3K/AKT pathways in miR-147-/- mice in radioprotection will thus benefit current knowledge of miR-147 while also informing efforts to improve radioprotection.

Abstract
Radiation injury from medical, accidental, or intentional sources can induce acute and long-term hepatic dysregulation, fibrosis, and cancer. This long-term hepatic dysregulation decreases quality of life and may lead to death. Our goal in this study is to determine acute changes in biological pathways and discover potential RNA biomarkers predictive of radiation injury. We performed whole transcriptome microarray analysis of mouse liver tissue (C57BL/6 J) 48 h after whole-body irradiation with 1, 2, 4, 8, and 12 Gray to identify significant expression changes in mRNAs, lncRNAs, and miRNAs, We also validated changes in specific RNAs through qRT-PCR. We used Ingenuity Pathway Analysis (IPA) to identify pathways associated with gene expression changes. We observed significant dysregulation of multiple mRNAs across all doses. In contrast, miRNA dysregulation was observed upwards of 2 Gray. The most significantly upregulated mRNAs function as tumor suppressors: Cdkn1a, Phlda3, and Eda2r. The most significantly downregulated mRNAs were involved in hemoglobin synthesis, inflammation, and mitochondrial function including multiple members of Hbb and Hba. The most significantly upregulated miRNA included: miR-34a-5p, miR-3102-5p, and miR-3960, while miR-342-3p, miR-142a-3p, and miR-223-3p were most significantly downregulated. IPA predicted activation of cell cycle checkpoint control pathways and inhibition of pathways relevant to inflammation and erythropoietin. Clarifying expression of mRNA, miRNA and lncRNA at a short time point (48 h) offers insight into potential biomarkers, including radiation markers shared across organs and animal models. This information, once validated in human models, can aid in development of bio-dosimetry biomarkers, and furthers our understanding of acute pathway dysregulation.

Transcriptome Profiling Unveils a Critical Role of IL-17 Signaling-Mediated Inflammation in Radiation-Induced Esophageal Injury in Rats. Dose Response 2022; 20:15593258221104609.

Abstract
Elucidation of the molecular mechanisms involving the initiation and progression
of radiation-induced esophageal injury (RIEI) is important for prevention and
treatment. Despite ongoing advances, the underlying mechanisms controlling RIEI
remain largely unknown. In the present study, RNA-seq was performed to
characterize mRNA profiles of the irradiated rat esophagus exposed to 0, 25, or
35 Gy irradiation. Bioinformatics analyses including dose-dependent
differentially expressed genes (DEGs), Gene Ontology (GO), Kyoto Encyclopedia of
Gene and Genome (KEGG) pathway, protein-protein interaction (PPI) network, and
immune infiltration were performed. 134 DEGs were screened out with a
dose-dependent manner (35 Gy > 25 Gy > control, or 35 Gy < 25 Gy <
control). GO and KEGG analyses showed that the most significant mechanism was
IL-17 signaling-mediated inflammatory response. 5 hub genes, Ccl11, Cxcl3,
Il17a, S100a8, and S100a9, were identified through the intersection of the DEGs
involved in inflammatory response, IL-17 pathway, and PPI network. Additionally,
immune infiltration analysis showed the activation of macrophages, monocytes, T
cells, NKT cells, and neutrophils, among which macrophages, monocytes, and
neutrophils might be the main sources of S100a8 and S100a9. Thus, these findings
further our understanding on the molecular biology of RIEI and may help develop
more effective therapeutic strategies.

Abstract
Acute urethral injuries caused by urethral endoscopy and other mechanical injuries are the main reasons for secondary infection and late urethral stricture. However, there are no studies to explore the transcriptomic changes in urethral injury and the molecular mechanism of urethral injury, which is important for the treatment and cure of urethral injury. Therefore, we used RNA-seq and sRNA-seq profiles from normal and injured urethral tissues to identify and characterize differentially expressed mRNAs and miRNAs. In total, we found 166 differentially expressed mRNAs, of which 69 were upregulated, and 97 were downregulated in injured urethral tissues. The differentially expressed mRNAs were mainly involved in the positive regulation of epithelial cell differentiation, focal adhesion, cell adhesion molecules, protein activation cascade, complement activation, complement and coagulation cascades, and chemokine-mediated signaling pathway. Additionally, we found six upregulated and four downregulated miRNAs, respectively, in the injured urethral tissues. Notably, their target genes were involved in the vascular endothelial growth factor receptor 2 binding, PI3k-Akt signaling pathway, and Notch signaling pathway. In summary, our results suggest that the cell damage response induced by mechanical injury activates the pathological immune response in a variety of ways in injured urethral tissues.

Abstract
Radiation-induced esophageal injury (RIEL) is a major dose-limiting complication of radiotherapy, especially for esophageal and thoracic cancers. RIEL is a multi-factorial and multi-step process, which is regulated by a complex network of DNA, RNA, protein and metabolite. However, it is unclear which esophageal metabolites are altered by ionizing radiation and how these changes affect RIEL progression. In this work, we established a rat model of RIEL with 0-40 Gy X-ray irradiation. Esophageal irradiation using ≥25 Gy induced significant changes to rats, such as body weight, food intake, water intake and esophageal structure. The metabolic changes and related pathways of rat esophageal metabolites were investigated by liquid chromatography-mass spectrometry (LC-MS). One hundred eighty metabolites showed an up-regulation in a dose-dependent manner (35 Gy ≥ 25 Gy > controls), and 199 metabolites were downregulated with increasing radiation dose (35 Gy ≤ 25 Gy < controls). The KEGG analysis showed that ionizing radiation seriously disrupted multiple metabolic pathways, and arachidonic acid metabolism was the most significantly enriched pathway. 20 metabolites were dysregulated in arachidonic acid metabolism, including up-regulation of five prostaglandins (PGA2, PGJ2, PGD2, PGH2, and PGI2) in 25 or 35 Gy groups. Cyclooxygenase-2 (COX-2), the key enzyme in catalyzing the biosynthesis of prostaglandins from arachidonic acid, was highly expressed in the esophagus of irradiated rats. Additionally, receiver operating characteristic (ROC) curve analysis revealed that PGJ2 may serve as a promising tissue biomarker for RIEL diagnosis. Taken together, these findings indicate that ionizing radiation induces esophageal metabolic alterations, which advance our understanding of the pathophysiology of RIEL from the perspective of metabolism.

Abstract
Radiation-induced lung injury (RILI) can be challenging for thoracic radiotherapy, thus investigating its mechanisms of related pathophysiological process is needed. Long noncoding RNAs (lncRNAs) was found to participate in normal tissue damage induced by ionizing irradiation. Here, we first profiled the dysregulation of lncRNAs, microRNAs (miRNAs), and messenger RNAs (mRNAs) of RILI in mice model receiving 12 Gy thoracic irradiation. The lung tissue was collected 48 hours after irradiation, after which an RNA library was built by RNA sequencing. Compared with the control group, 461 mRNAs and 401 lncRNAs were significantly upregulated, while 936 mRNAs and 501 lncRNAs were significantly downregulated. Then we predicted target miRNAs of the dysregulated lncRNAs and the target mRNAs of these miRNAs. Next, functional annotations of these target mRNAs were performed. Results showed some pathways apparently dysregulated, such as Th1 and Th2 cell differentiation, Th17 cell differentiation, and hematopoietic cell lineage. Through this study, we also highlighted that T helpers could be vital in RILI through lncRNA-miRNA-mRNA network, therefore causing fibrosis, indicating that RNA dysregulation in early stage of RILI may cause severe late complications. Thus, research on the target mechanism and early intervention of lncRNAs with associated competing endogenous RNA network will benefit the treatment of RILI.
